Vibration
• The chiller does not require vibration isolation on the mounting for the chiller to operate
normally.
• The motors in the chiller are hard mounted to the metal structure of the chiller. They are not
internally isolated.
• It is common for the chiller to be hard mounted directly to a pad on grade, roof curb, or
perimeter beam system.
• If vibration transmission to the building structure is a concern, an engineer should provide a
detailed specification for vibration damping.
• There are two common approaches
o Rubber or synthetic pads between the chiller and the mounting
o Spring vibration isolators. These cannot be installed directly between the chiller and the
mounting. The chiller must be mounted on a perimeter beam. The spring vibration
isolators can be installed between the beam and the mounting.
OSHPD: If OSHPD compliance is required and isolators are used, the spring isolators must comply
with Haskris OSHPD OSP-0673 file.
